Please refer to FIG. 1 to FIG. 5. FIG. 1 is a schematic diagram of a stroller 1 according to an embodiment of the present invention. FIG. 2 and FIG. 3 are lateral view diagrams of the stroller 1 in different states according to the embodiment of the present invention. FIG. 4 and FIG. 5 are partial diagrams of the stroller 1 at different views according to the embodiment of the present invention. As shown in FIG. 1 to FIG. 5, the stroller 1 includes a frame 11 and a basket 12 disposed on the frame 11. The basket 12 includes two tube mounts 121, a first tube member 122, a second tube member 123 and a basket covering 124. The two tube mounts 121 are disposed on the frame 11 and located at two lateral sides of the frame 11. The first tube member 122 is connected to the two tube mounts 121. The second tube member 123 is rotatably connected to the two tube mounts 121 and switchable relative to the frame 11 between an unfolded position as shown in FIG. 2 and a folded position as shown in FIG. 3. The basket covering 124 is disposed on the first tube member 122 and the second tube member 123. A storage space is enclosed by the basket covering 124, and a volume of the storage space is adjustable by rotation of the second tube member 123 relative to the frame 11. When the second tube member 123 is rotated from the folded position as shown in FIG. 3 to the unfolded position as shown in FIG. 2, the basket covering 124 is gradually expanded, so that the volume of the storage space enclosed by the basket covering 124 is increased. When the second tube member 123 is rotated from the unfolded position as shown in FIG. 2 to the folded position as shown in FIG. 3, the basket covering 124 is gradually collapsed, so that the volume of the storage space enclosed by the basket covering 124 is decreased. However, the number of the tube mount is not limited to this embodiment. For example, in another embodiment, there can be only one tube mount located at one side of the frame.

Please refer to FIG. 1 to FIG. 10. FIG. 6 is a partial diagram of the basket 12 according to the embodiment of the present invention. FIG. 7 is a partial exploded diagram of the basket 12 according to the embodiment of the present invention. FIG. 8 is a partial internal structural diagram of the basket 12 according to the embodiment of the present invention. FIG. 9 and FIG. 10 are partial internal structural diagrams of the basket 12 in different states according to the embodiment of the present invention. As shown in FIG. 1 to FIG. 10, the two tube mounts 121 located at the two lateral sides of the frame 11 can have the same structure. The tube mount 121 at one lateral side of the frame 11 is introduced as follows for simplicity. The tube mount 121 includes a first mount member 1211 and a second mount member 1212. The first mount member 1211 is disposed on the frame 11 and connected to the first tube member 122. The second mount member 1212 is disposed on the second tube member 123 and rotatably combined with the first mount member 1211. The second tube member 123 is rotatable relative to the frame 11 by rotation of the second mount member 1212 relative to the first mount member 1211.

Furthermore, the first mount member 1211 includes a housing 1211A. The second mount member 1212 includes a hub 1212A rotatably combined with the housing 1211A. A plurality of first ribs 1211B is formed on at least one portion of an inner wall of the housing 1211A. A plurality of second ribs 1212B is formed on at least one portion of an outer wall of the hub 1212A. The first mount member 1211 and the second mount member 1212 engage with each other by the plurality of first ribs 1211B and the plurality of second ribs 1212B for positioning the second tube member 123 at a desired position between the folded position and the unfolded position. In other words, the second tube member 123 can be positioned at any position between the unfolded position and the folded position by positioning the second mount member 1212 relative to the first mount member 1211 with engagement of the plurality of first ribs 1211B and the plurality of the second ribs 1212B, which achieves a purpose of multistage adjustment of the volume of the storage space.

Preferably, in this embodiment, the plurality of first ribs 1211B can be formed around at least one portion of the inner wall of the housing 1211A and made of plastic material, and the plurality of second ribs 1212B can be formed around at least one portion of the outer wall of the hub 1212A and made of plastic material. Furthermore, a cross section of each of the plurality of first rib 1211B and a cross section of each of the plurality of second rib 1212B can be formed in arc shapes. In such a way, the first ribs 1211B and the second ribs 1212B can be forced to be elastically deflected to disengage from each other for allowing the rotation of the second mount member 1212 relative to the first mount member 1211 when the second tube member 123 is operated by a user. Besides, the first ribs 1211B and the second ribs 1212B can be elastically recovered to engage with each other for positioning the second mount member 1212 relative to the first mount member 1211 when the second tube member 123 is released by the user. Therefore, no additional releasing mechanism for disengaging the first ribs from the second ribs is required, which simplifies operation and brings convenience in use.

Please further refer to FIG. 1 to FIG. 5. In order for easy storage and transportation of the stroller 1, the frame 11 is foldable and includes a handle 111, a front foot 112, a rear foot 113 and a seat 114 installed on the handle 111. The first mount member 1211 of the tube mount 121 is disposed on the front foot 112, and the tube mount 121 further includes a third mount member 1213 disposed on the rear foot 113 and rotatably combined with the first mount member 1211 and the handle 113. In other words, the front foot 112 is rotatably connected to the rear foot 113 by the two tube mounts 121, and the handle 111 is rotatably connected to the rear foot 113 by the two tube mounts 121.

In addition, in order to facilitate folding operation of the frame 11, the frame 11 further includes two link members 115. Each link member 115 is movably connected to the handle 111 and the first mount member 1211 of the corresponding tube mount 121. The handle 111 drives the front foot 112 to rotate toward the rear foot 113 by the two link members 115 when the handle 111 rotates relative to the third mount member 1213 to move toward the rear foot 113. However, the present invention is not limited to this embodiment. For example, in another embodiment, there can be no link member or only one link member located at one lateral side. Alternatively, there can be no third mount member, and the handle can be directly pivoted to the front foot or the rear foot accordingly.

In contrast to the prior art, the present invention utilizes the plurality of first ribs on the first mount member and the plurality of second ribs on the second mount member which are preferably made of the plastic material, to allow or restrain rotating movement of the second mount member relative to the first mount member. Therefore, the second tube member can be positioned at any position between the unfolded position and the folded position by positioning the second mount member relative to the first mount member with engagement of the plurality of first ribs and the plurality of the second ribs, which achieves a purpose of a multistage adjustment of the volume of the storage space. Furthermore, the plurality of first ribs and the plurality of second ribs can be forced to be elastically deflected to disengage from each other for allowing the rotating movement of the second mount member relative to the first mount member when the second tube member is operated to rotate relative to the frame.
